Cars with spikes are limited to 50kmh in Germany.
Note to self: Grsetzbücher nicht mehr aus der grabbelkiste vor der buchhandlung mitnehmen.
It helps to a certain degree to adjust the tire pressure.On dry roads I ride with high tire pressure, and when it's really icy, it helps to lower the pressure as much as possible. A second wheelset that can be changed quickly is of course ideal.
@willemsst @jwildeboer In my experience they are rather inconvenient in normal conditions: high rolling resistance, noisy, slippery on metal and cobblestone.
As Jan already pointed out, best to have a separate winter bike in locations with only a few days of frost/snow per year. I use an old, rather crappy bike of mine for that, so no big cost involved.
@jwildeboer I haven't used them in last winter and this winter at all but I love the freedom they give when everybody else just slides!
